Yes...shading of zirconia is very important. And more importantly is consistent shading. If the milling center consistently gives me the wrong shades you can only imagine the problems it...See more causes for a lab. The lab either needs to correct the shade or have the work remilled which is could delay seating of the crown.
I have availability to work on applying the ceramic on your frames. My build up utilizes similar methods as Oliver Brix. Multiple layer application with life-like anatomy. High end results with less chair time for the patient. Please contact me if interested. Thank you, Stephan KresseAdded November 20, 2013
